Why doesn't my battery charge? Why doesn't the charger's light come on?


Hi Suzanne! Follow these steps to check that your charger and battery are working properly.

1. Unplug the charger for at least 30 seconds.
2. Plug the charger back in. The blue light on the charger should flash once.

If the blue light flashes once this is an indication that the charger is still functioning properly. If the blue light does not flash, the charger will need to be replaced. Follow this link to order a replacement charger. LiNX Battery Charger

3. Place the battery in the vacuum and turn it on for 30 seconds. (even if it does not turn on or powers off)
4. Turn the vacuum off.
5. Remove the battery and place it in the charger.

If the light on the charger is solid blue this is an indication that the battery has been reset. Allow 3-4 hours for the battery to fully charge. The blue light will start to blink slowly to indicate the battery is fully charged.

If the light on the charger is flashing blue or there is no light at all this can mean that your battery needs to be replaced. Follow the link to order a replacement battery. LiNX Lithium Ion Battery

Hope this helps!

Delta CL 180 model charger turns on when you plug in and the yellow light comes on but when you put the battery in to charge the lights go out?


If all lights go out after the battery is inserted, the charger has entered pre-charge mode. In approximately 5-10 minutes, the orange and red lights should turn on indicating that fast charge has been initiated. If all lights remain off after 15 minutes, remove the battery. The orange light should glow. Reinsert the battery. If the orange light goes out when the battery is inserted and all lights remain off for 15 minutes the battery should be replaced.

Hope this helps.

My power cord is OK and a blue light is seen where it plugs in. However, I can't turn it on. I had it on a few times yesterday and the battery check says battery is "good". However, battery is at 0%...


I have had this issue with a few HP laptops.
Does the lighning bolt light up on the laptop to indicate charging?
Maybe try unplugging the power adapter and battery, press and hold the Power button for 30 seconds, pug in the battery and power adapter. In Windows click Start > Settings > Control Panel > Power Options. Click on Power Meter Tab and check the startus of the battery (i.e. Charging, not present etc)

HP Pavilion dv9700t battery dead, faint blue flash from plug


Check your mains adapter plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.

If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. I suggest you get a quote first.

Pavilion dv6000 when power button is pressed,


Have you tried to boot the laptop with the power cable connected? Is the charging indicator on when you connect it to the adapter? If the charging indicator does not light up, check if your adapter output and try booting it with the power cable connected.

Hp pavillion will not turn on, took battery out and put back in still not working. blue light around power cord on and blue lightening bolt flashes


Hi Iceprincess5

The three flashing lights indicate the battery is dead. Since it still wont power up with the cable plugged in I'd say the port has gone. Try wiggling the adapter about in the port to see if it begins to charge. If not then you would need to take it to a laptop repair centre to get a new dc port soldered on or buy a docking station.

No problem? ?? HP dv8230 status indicator lights flashing.


I believe this would mean that your battery either has a low charge or if you have the AC power cord plugged in, it could mean your battery is bad and won't take a charge
